[SunRescue] Re: Multics

[Joshua D. Boyd]

What unix is written in C++?  Linux and *bsd are in C.  Most machine
specific bits are still written in C, with only small amounts of really
low level stuff in asm (if I remeber, it is less than 1000 lines of intel
asm, other platforms probablly have less).
